Abstract
The utility model belongs to mechanical machining equipment. The main structure is that a cutterhead body with a turning tool is a structure which can rotate integrally with a power shaft and can move along axial direction relative to the power shaft. The utility model is also provided with a driving mechanism which impels the cutterhead body move along axial direction. The cutterhead body is provided with two concentric gears with different diameters, and a transverse rack bar which moves transversely under the action of the gears. The front end of the power shaft is connected with longitudinal rack bar which is engaged with the gears. The pipe beveling machine of expanding method provided by the utility model can conveniently process a bevel with an arbitrary curved surface, and has the advantages of simple structure and convenient operation.
Description
The utility model belongs to machining equipment, mainly proposes a kind of generating pipe fitting bevelling machine.
Pipe fitting such as petrochemical industry, electric power junction need process different grooves, can guarantee the welding quality of junction.Present domestic nothing has the universal machine tools process equipment can finish various groove machining, general small piece can on the engine lathe, big part makes pipe fitting rotate on vertical lathe, lathe tool is walked out the groove shape, finishes turning processing.The defective that this processing mode exists is: the engine lathe restricted diameter, and the height-limited cost of vertical lathe is too high, and bending radius is excessive, and too high pipe fitting lathe can't be processed.Have to otherwise replace; As cutting out groove, use the emery wheel smoothing then with gas cutting.Substitute unit head with boring, car, mill etc. in addition and take method of forming processing, pipe fitting does not change, and allows the cutter rotation only move axially with pipe fitting, and it is consistent with the groove shape that cutter is worn into, and a cutter is processed into pipe fitting groove shape.But excessive because of cutting width, pipe fitting, cutter, lathe easily shake, collapse cutter, damage lathe; Motor reel also often twists off, and the groove of processing pipe fitting easily forms the washboard-type tool marks, needs emery wheel to fix, and both takes a lot of work, and can not ensure the quality of products again.
The purpose of this utility model promptly is to propose a kind of generating pipe fitting bevelling machine, makes it can process the groove of arbitrary surface easily on pipe fitting, and makes it have simple in structure, convenience operation.
The utility model is finished the technical scheme that its invention task takes: the cutter head that has a lathe tool for line shaft one rotation and can axially movable structure, and be provided with one and promote the axially movable driving mechanism of cutter head, cutter head is provided with two concentric gears, also is provided with the horizontal tooth bar that laterally moves under gearing; The line shaft front end is connected with the longitudinal rack with gears engaged.
Two gear diameters that are provided with on the cutter head are identical.
Two gear diameters that are provided with on the cutter head are inequality.
Setting moves axially pushing mechanism by the line shaft that worm gear, worm screw and leading screw, screw constitute.
The utility model is when operation, the operation worm screw drives worm gear and leading screw rotates, owing to the fixed structure of screw makes leading screw make line shaft by bearing and the longitudinal rack that is connected in the line shaft front end moves axially, the gear, the tooth bar that promote on the cutter head move radially lathe tool, finish the machining of end face.
Operation make cutterhead axial displacement driving mechanism, cutter head and on Gear axial displacement the time, gear rotates the drive horizontal rack makes cutter traverse to moving, cutter axially and laterally moves simultaneously, formed resultant motion is an oblique line, angle [alpha], tg α=lathe tool move axially the horizontal translational speed of speed/lathe tool.
The utility model can be finished the groove cutting of pipe fitting different angles easily when operation, the structural design of proposition is comparatively advanced, novel, and practicality is stronger.
Embodiment:
Accompanying drawing 1 is the utility model structural representation.
With reference to accompanying drawing its structure is further specified:
As shown in drawings: the driving rotating mechanism of line shaft 6 includes motor 26, gearbox 25, gear 23,24 and hub splines 7, motor 26 drives line shaft 6 and rotates through gearbox 25, gear 23,24, hub splines 7, rotate with the main shaft 12 of line shaft 6 splined thereupon, with main shaft 12 joining cutterheads 13, horizontal rack 17 and lathe tool 18 rotate together.Gear 15,16 is positioned on the axle 20 in the cutterhead 13 for two gears of different-diameter, with key 21 gear 15,16 and axle 21 is fixed.Line shaft 6 axially movable pushing mechanisms are: worm screw 3, worm gear 4 and singly-bound axle sleeve 5, leading screw 2 and screw 1, operation worm screw 3 is rotated, drive worm gear 4, singly-bound axle sleeve 5, leading screw 2 rotations, screw 1 links to each other motionless with body, leading screw 2 rotating middle shafts are to moving, the longitudinal rack 14 that makes line shaft 6 and be connected in its front end through bearing 27 moves axially, gear 15 driven gears 16 that longitudinal rack 14 promotes on the cutter head 13 rotate, the horizontal tooth bar 17 that gear 16 drives on the cutter head laterally moves lathe tool 18, finishes building up by welding processing.
(gear 8 links to each other with operating grip through worm and gear operation gear 8, do not draw among the figure), driving band rack sleeve 9 moves axially, through bearing 10, (main shaft 12 links to each other with line shaft 6 splines to promote main shaft 12, consubstantiality rotates but can move forward and backward), cutterhead 13, gear 15,16, horizontal rack 17, cutter 18 move axially; Axially motionless because of longitudinal rack 14, gear 15,16 just rotates, and gear 16 drives horizontal rack 17, cutter 18 and laterally moves, and cutter 18 moves axially simultaneously and laterally moves, and its resultant motion is an oblique line.
The beveling machine of generating processing arbitrary surface is called for short generating (synthetic method) finished edge machine, can process the compound groove of arbitrary shape with a simple shape lathe tool, pipe fitting does not change, keep flat that to have solved pipe fitting too high, bending radius is long, the difficult problem that the vertical lathe engine lathe can't be processed, can horizontal (directly) in the lathe tool rotation to feed, again can axle (indulging) to feed, tiltedly feed and walk the arbitrary shape curve.
Change gear 15,16 reference diameters, lathe tool obtain different proportion and move axially speed and horizontal translational speed, finish different bevel angles.
With mechanical means or handle worm gear 3, gear 8 respectively with two stepper motors and rotate in varing proportions, it can finish different bevel angles or circular arc machining.
